The hierarchical arrangement of this phylogeny provides a comparative and predictive framework for all fundamental and applied biology. Our understanding of the Tree of Life has advanced rapidly over the past decade fuelled by enormous progress in the fields of genomics and information technology.

Although well studied, the evolutionary relationships among major avian groups are contentious.The very nature of the evolutionary history of organisms and the limitations of current phylogenetic reconstruction methods mean that parts of the tree of life might prove difficult, if not impossible, to resolve with confidence.Phylogenomics is useful for resolving difficult phylogenies and for verifying or overturning relationships created on the basis of single genes.

To do phylogenomics analysis of birds, the genomes presented here were sequenced, de novo assembled and annotated for functional elements. These genomes will be helpful to construct the evolutionary history of birds, which has the potential to provide answers to several outstanding fundamental evolutionary questions.
